T all whom it may concern.

Be it known that I, TIMOTHY FRANKLIN Prmno, a citizen of the UnitedStates, and a resident of Tuckerton, in the county of Ocean and State ofNew Jersey, have invented a new and Improved Ice-Making Apparatus, ofwhich the following is a full, clear, and exact description.

This invention relates to ice making machinery and has particularreference to apparatus employed in connection with the manufacture ofice by freezing the same in cans plunged into a tank of brine, the typeof devices to which this invention relates being set forth in myprevious Patent, No. 1,055,980, issued to me on the 11th of March, 1913.

Among the special. objects of this invention is to provide an apparatusinvolving the use of a pump or an analogous means in connection witheach can of water for the purpose of agitating the water in the canduring the process of freezing so as to prevent the incarceration of airbubbles which cause the ice to have a snowy appearance and hence renderthe ice less salable. I have discovered and have proved in practice thatthe cloudy or snowy appearance of the ice due to the inclosed airbubbles may be obviated by keeping the surface of the water in the canopen and causing the water to be circulated more or less while thefreezing is taking place at the bottom of the can upwardly toward thetop.

A further object of the invention is to so arrange the several agitatingpumps with respect to the brine tank as to simplify the manipulation ofthe pump connections and nor .zles with reference to the introductionand withdrawal of the cans into and from said tank without the necessityof making any disconnections of the devices.

A still further object of the invention is to simplify and improve thevarious details of mechanical devices.

The foregoing and other objects of the invention will hereinafter bemore fully described and claimed and illustrated in the drawings forminga part of this specification in which like characters of referenceindicate corresponding parts in all the views, and in which- Figure 1 isa plan view showing the re-. lation of the pump mechanism to the icecans and framework at the top of the brine tank; Fig. 2 is a sideelevation of the same,

parts being in section; Fig. 3 is a plan view of a larger portion of thebrine tank and in dicatmg the relation thereto of the agitatmgmechanism; Fig. 4 is a plan view of a section of a pump rod, a clampsecured thereto, and a pair of pistons connected to sa d clamp; Fig. 5is a vertical sectional cletail on the line 55 of Fig. 3, indicating themeans for varying the stroke of the pump pistons; Fig. 6 is a viewangles to Fig. 5 from the plane indicated by the line 66 of Fig. 3; Fig.7 is a detail of the pump piston packing; Fig. 8 is a detail of theagitator nozzle; Fig. 9 is a plan View of the upper end of the nozzleconnection described below, and Fig. 10 is a detail of the connectionbetween a driving eccentric and a pump rod. 1

The several parts of the device may be made of any suitable materialsand the relative sizes and proportions as well as the general layout ofthe device may be varied to a considerable extent without departing fromthe spirit of the invention hereinafter more fully set forth andspecifically claimed.

I show at 10 a brine tank having any suitable number or size ofcompartments 11 formed therein by means of the rectangular framework 12,each of said compartments being designed to accommodate a well knownform of freezing can 13. The cans 13 are intended to be inserted intothe brine through the rectangular spaces of the framework and there heldin place during the freezing operation according to the well knownprocess.

Extending longitudinally of the brine tank framework 12 are rails 14.Each of these rails extends along the longitudinal rib separating onelongitudinal row of compartments 11 from the next. In other words, thenumber of rails 14 is preferably just one half of the number oflongitudinal rows of compartments. These rails 14 are fixed in positionwith respect to the frame 12 in any suitable manner and are strong andrigid enough to withstand not only the trafiic above the brine tank dueto the manipulation of the cans of water and ice, but also are intendedto carry on their under surface the pump portions of the agitatormechanism. As shown in Figs. 1, 2 and 3, that portion of the rail 14Lbetween each two adjacent compartments 11 is fitted with a pair of pumpcylinders 15 extending longitudinally of the rail in alineat right"inders are secured permanently and rigidly in position by means ofclamps 16 and- 17 secured to the under surface of said rail. Eachcylinder is provided with a piston'lS connected to and operated by apiston rod 19. The piston rods 19 of each pair of pumps terminateadjacent each other and are connected detachably to a clamp 20 in thespace, above referred to, between the cylinders. Said clamp is shownprovided with a pair of spaced jaws 21, each having an open side. Eachpiston rod is fitted at its end with a fixed head '22 which may be inthe form of a nut upset or riveted in place and adapted to lie upon theinner face of one of said jaws 21, the rod being adapted to slip in orout of said open side of the jaw. WVhen the piston rod is put in placeas just by means of nuts 23 and 24. The piston is so made as to includea flexible bucket 25 adapted to be connected to the end of thepistonirod 19' and provided on its inner surface with an annular seat orgroove 26 into which is adapted to be sprung a split ring 27 whichserves to keep the outer edge of. the bucket spread"outwardlyinto closefitting engagement with the inner surface of the cylinder.

'Located at any convenient place in proximity to the brine tank is apower shaft128 supported in bearings 29 substantially par allel to oneside of the tank. This shaft is adapted to be driven by a power belt orchain indicated at 30. This shaft has mounted thereon any suitablenumber of adjustable eccentrics 31, such number preferably coincidingwith the number of rails 14 above described. Each eccentric 31 isprovided with a strap 32 to which is connected apump rod 33' whichextends alongpreferablybeneath the porresponding rail 14, and the pumpclamps 20 are securedrigidly to said rod by means of clamps 3 1. Theseveral eccentrics connected to the power shaft 28 are preferablystaggered [so that me power required for operating all of the pumps atthe same time will be distributed or equalized as much as possiblethroughout the system. In order to accommodate the apparatus to tanksorsystems of varying sizes and also to vary the operation of some of thepumps without disturbing others and for other reasons, I provide ,meansfor readily varying the throw of the eccentrics,

and hence the stroke of the pumps without stopping the engine orinterfering with the ordinary-or regular speed of the power shaft. As asimple and effective means for accomplishing this result, I connect eacheccentric 31 to the power shaft 28 through a block 35 lreyed tojtheshaft and'havingslidas shown in Fig. 5.

described, it will be set and locked able connection with the eccentricdisk 31, In other words, the center of the disk or eccentric isadjustable radially toward or from the axis of the shaft and block 35.To this end I provide a screw having threaded engagement in a stationarynut 37 in the end of the slot 31 opposite the block 35. Said screw 36has connected to it at its inner end a miter gear 38 extending laterallyfrom said block, as shown in Fig. 6, and meshing with a pair of similargears 39. Each of said gears 39 is sleeved upon the power shaft and hasconnected to it a hand wheel 4:0 concentric with said shaft. In normaloperation said hand wheel and eccentric, and the devices connectedbetween the same, all rotate with the shaft, and the stroke of the pumpscorresponds to the eccentricity or throw of the eccentric in anyadjustment. In order, therefore, to vary the eccentricity of theeccentric at any station, it is but necessary for the operator to graspone of the hand wheels 40, and either hold it from rotation while thepower shaft is operating, or otherwise manipulate it for the purpose ofoperatin the screw 36 to cause the radial shifting o the eccentric whilethe shaft is running. The pump rods 33 are preferably guided andsupported in bearings 33 formed in the cross pieces of the frame 12.

Connected to the outer end of each pump cylinder is atubular arm 41, theconnection being through a hinge joint 4C2 providing for the swinging ofthe arm in a horizontal plane beneath the pump and rail thereover; Tothe opposite end of the arm -11 is connected a nozzle arm 43 having atelescopic section 44 fitted thereon. Said nozzle arm 43 is connectedalso by a hinge joint 1 .5, as shown in Figs. 1 and 2, adapting it toswing in vertical planes whereby it may not only be adjusted verticallywith respect to the depth of the water in the can being treated, but itmay be swung upwardly to clear the upper edge of the can and then swungin the horizontal plane with the arm ll out of the vertical range of thecan, enabling the can to'be inserted or withdrawn without any danger ofinterference with the pump arm connections. As one convenient andsatisfactory means for connecting the telescopic nozzle 44 to the otherportion of the nozzle arm I provide the upper end of said nozzle with apair of spring fingers 46 formed integral with said nozzle by meanseerieformed adjacent the lower end of the stationary member of the arm 43,formed by a circumferential groove 50. By beveling the free ends of thefingers, as shown at 46, the nozzle may be easily slipped upon the othermember, and after being applied thereon, may be slipped along to anydesired distance, but the form and arrange ment of the fingers 46 willprevent the accidental removal of the nozzle from the other member byengagement with said shoulder 49. The lower end of the member 48 ispreferably flared or spread slightly, as indicated at 43, for thepurpose of making a substantially close fit with the inner surface ofthe nozzle 44 whereby special packing is avoided. The lower end of thenozzle is provided with an elbow 51 for the purpose of directing thecurrents of water as may be required.

The operation of the device may be briefly described as follows: l/Viththe power shaft in rotation in either direction and the several pumprods 33 being reciprocated thereby through the eccentrics 3l, the pumppistons will all be reciprocated according to the eccentricity or throwof the eccentrics as above described. A can of water may be introducedinto any vacant compartment 11 after the arm 41 and its nozzleconnection 43 have been swung in a horizontal plane beneath the rail 14.After the can has been set in the brine and secured in any well knownmanner, said arm 43 is swung outwardly to or toward the positionindicated in Fig. 1, and the nozzle arm 43 swung downwardly into or inthe position shown in Fig. 2 with the nozzle 44 extended so as to reachbeneath the surface of the water which, in practice, must be far enoughbelow the upper edge of the can to provide for the necessary expansionduring the freezing. By operating the pumps at a comparatively slowspeed, the water at the center of the top of the can will be kept open,preventing the freezing over at this point while the ice is forming atthe sides and bottom thereof. Any sediment which may be in the waterwill collect in the pocket or cap resulting adjacent the top when thefreezing is nearly completed, and such dirty water, if desired, may beremoved therefrom by any suitable or convenient means (not shown) andthe cavity, upon being filled with clear water,

will insure a perfectly clean clear block of ice when finished.
